What is the primary function of the Peripheral Nervous System?

The primary function of the Peripheral Nervous System (PNS) is to connect the Central Nervous System (CNS), which consists of the brain and spinal cord, to the rest of the body. This connection allows the brain and spinal cord to communicate with muscles, organs, and skin, facilitating sensory input and motor output. The PNS is essential for transmitting signals that direct bodily functions, sensations, and movements.

While the PNS plays a role in processing sensory information and regulating some internal body functions, its overarching purpose is to establish the link between the CNS and various parts of the body. This connectivity is crucial for the integration and coordination of actions and responses to stimuli.
